Development of digital refraction-contrast tomosynthesis

折射-对比度数字乳腺断层成像系统是与X射线光学相结合的用于X射线暗场成像和数字断层合成的系统，其目的是在切片图像中可视化乳腺等软组织的内部结构。我们成功地重建了吸收对比度图像对比度较小的乳腺组织断层图像，以描绘乳腺肿块的内部结构和部分钙化分泌物区域。

Refraction-contrast digital breast tomosynthesis system was developed in combination with X-ray optics for X-ray dark-field imaging and digital tomosynthesis, by which we aim at visualizing internal structures of soft tissues such as breast in slice images. We successfully reconstructed tomograms of breast tissues, which have little image contrast in absorption contrast images, to depict internal structures of breast mass and some of regions with calcific secretion.
